The title is Das Kapital. Kritik der politischen Oekonomie (not oekonomic) as can be seen on the original title page.

This is the second edition of 1872 (the first being in 1867). Marx prepared a third, published by Engels in 1883, after the death of Marx earlier that year. The final version is the fourth edition (1890), with some corrections by Engels (partly based on the work of Eleanor Marx for the English translation).
It is recommended to work only on the final version (1890), but this edition is interesting to see the evolution from the first.
